I am adding a new item to the available select options in a modal box and updating the server. When I close the modal, i want to see the new added option in the select box and actually selecting it without refreshing the entire page, so just select box needs to be updated. Is this possible?
Page;
<select ng-model="scores" ng-options="score for score in options.scores" />
so on the model box, i add a new value to options.scores
Try wrapping your ng-model in a container object, to prevent any scope hierarchy issues.
ng-model="state.scores"
Where you defined state like:
$scope.state = {};
// then whenever you want to set your scores.
$scope.state.scores = ...
You should read up on angular's scope hierarchy. http://jimhoskins.com/2012/12/14/nested-scopes-in-angularjs.html

I have a reactive form and I am using Material Angular, with a tab group and the tab names comes from an array, I need to add the possibility of changing those tabs names for new ones. If a write a new title in the input I need to update the name of the tab label.
I’m getting the value from the input, but I can’t figure it out how to send it to the names of the tabs:
app.component.ts
this.newTitleArm = selection.formdata.titleTextArms;
console.log(this.newTitleArm);
STACKBLITZ
SCREENSHOT
Can you have a look at this Stackblits
Note that I have modified the submit method and have added
if(this.form.get('titleArms').value === 'changeArm'){
this.tabs[this.selected.value].name = this.form.get('titleTextArms').value;
}
Here I'm assigning the titleTextArms control value to selected tab name. You can get selected tab by this.tabs[this.selected.value]
Also added the if condition to check selection of radio button.
UPDATE:
since you have used tab names to create the text in the parent component.
In the submit method
need to do the tab name update before emitting the updateDataEvent.
submit(): void {
if (this.form.get('titleArms').value === 'changeArm') {
if (this.form.get('titleTextArms').value !== '') {
this.tabs[this.selected.value].name =
this.form.get('titleTextArms').value;
}
}
this.updateDataEvent.emit({
formdata: this.form.getRawValue(),
tabs: this.tabs,
});
}
The problem is that you are not updating the respective tab name anywhere, neither in your submit, nor in your updateData.
You submit the value, but you are not updating the tabs.
For example, in your submit method add this hard-coded update and then press the Save button:
this.tabs[0].name = "test";
Because now you updated the first tab's name, you should see the change.
Scenario is quite simple. I have edit view which comprises of select element with multiple selection. Select element looks as follows
<select class="selectpicker" multiple
ng-model="UserBeingEdited.UberTypes"
ng-options="uberType.Id as uberType.Name for uberType in UberTypes"></select>
</div>
If I press edit for specific user then showEditModal function is called and edit pop up shows up. User has his own UberTypes objects selected so I pick theirs Ids and assign to UserBeingEdited.UberTypes.
$scope.UserBeingEdited = { UberTypes: []};
$scope.showEditModal = function (user) {
for (var i = 0; i < user.UberTypes.length; i++) {
$scope.UserBeingEdited.UberTypes.push(user.UberTypes[i].Id);
}
$("#editUserModal").modal("show");
};
Unfortunately they are not selected, no matter what. Suprisingly, if I set values to property UserBeingEdited by the time of declaring then it works, items are selected.
$scope.UserBeingEdited = { UberTypes: [1,2]}; //this works
It seems like angular does not refresh selected items within UI.
EDIT:
I have two items: Uber1 and Uber2. Both items are selected but view does not reflect it. If I open drop down menu and select Uber2 it shows Uber1 selected, apparently Uber2 was selected and another click was treated as unselection. The same happens when I click Uber1 first, Uber2 shows as selected.
As above picture depicts, Uber2 is highlighted since I have just clicked it but it shows Uber1 as selected. Both were selected in User's UberTypes but view just simply does not mark them as selected.

I use bootstrap-select.js for select element and presumably this library causes such an error since without including it, it works fine.
Solution
After a while of struggle, I accidentally ran into below workaround. You need to call refresh on selectPicker and this has to be delayed otherwise it will bring no effect.
setTimeout(function () {
$('.selectpicker').selectpicker('refresh');
}, 100);
$("#editUserModal").modal("show");
I have a requirement to open a modal on click of input box. Modal contains list of countries with search bar, once modal is open it searches for text picked from input and shows filtered list. Now user can search for different country and select from filtered list, modal closes and value is added to input field. In code,
openCountryPickerModal($event) {
let modal = this.modalCtrl.create(CountryCodePickerComponent, {"searchValue":$event.target.value});
modal.onDidDismiss(data => {
if(data){
$event.target.value=data.countrySelected;
// Here: the value set to $event.target.value is not updating to input box's model emergencyContactInfo.currentPersonalAddress.country
}
});
modal.present();
}
and in template
<ion-input (click)="openCountryPickerModal($event)" [(ngModel)]="emergencyContactInfo.currentPersonalAddress.country" type="text" placeholder="Country" readonly></ion-input>
Now the problem is, though it appears value is changed in UI, but never updates value to model. Any special reason?
I tried many ways to solve this but nothing works and I appreciate help if any.
I have a textfield and would like to not make it read only if a value is selected from a shuttle (many options can be picked). I am using Jheadstart to create the page, but an adf solution works just as well as I can just insert that change into ta template.Normally I would use a binding and select the input value of of another field, but I am not sure what to select with the shuttle as a shuttle can have many selections.
To get the values from the shuttlebox inside a bean:
BindingContainer myBC = this.getBindings();
JUCtrlListBinding listBinding = (JUCtrlListBinding)myBC.get("ViewObject1"); //viewObject that populates the shuttflebox
Object str[] = listBinding.getSelectedValues();
if(str.length>0)
isTextBoxDisabled=false;
else
isTextBoxDisabled=true;
Then bind the Disabled property of the inputtext to myBean.isTextBoxDisabled
This would need a page submit in order to activate, so I'm guessing that's not what you are after.
If you want it to automatically update the values as their are moved around in the shuttle, you will have to use the ValueChangeListener property of the shuttle, in which to get the size of the selections.
public void selectValueChangeListener(ValueChangeEvent valueChangeEvent) {
ArrayList list = new ArrayList(Arrays.asList(valueChangeEvent.getNewValue()));
if(list.isEmpty())
isTextBoxDisabled=true;
else
isTextBoxDisabled=false;
//refresh the inputText component
AdfFacesContext.getCurrentInstance().addPartialTarget(myInputText);
}
Bear in mind the ValueChangeListener will only get processed via their bean method when the page is submitted. If you want the change processed when changing the value of the shuttle, set autoSubmit = true.
I'm trying to have a dropdown menu for the user to select the database table. I have defined few tables in db.py and I want the user the to select a particular table from a dropdown menu and insert entries. Right now I use SQLFORM:
def index():
form=SQLFORM(db.selectedtable) #want to change the table name#
if form.process().accepted:
response.flash = 'form accepted'
elif form.errors:
response.flash = 'form has errors'
else:
response.flash = 'please fill out the form'
return dict(form=form)
I need the user to select 'selectedtable' value from a dropdown list that shows all the available tables in the DB. I do not necessarily want to retrieve the table values from DB. I am OK with defining a list with the available tables and the dropdown menu can pull the table names from that list.
So far I only found IS_IN_DB to automatically create a dropdown and PluginDropdown() but that does not serve my purpose. If soemebody can direct me to the proper way of handling this task I'd be really thankful.
Regards.
Update:
After Anthony's suggession I tried the following with , as I'm not that familiar with JS.
{{extend 'layout.html'}}
{{select='NONE'}}
<form>
<select>
{{for item in TOOLS:}}
<option value="{{select=item}}">{{=item}}</option>{{pass}}
</select>
<input type="submit" value="Go!"/>
</form>
<h2>Input form</h2>
{{=form}}
<h2>{{=select}}</h2>
As you might see this doesn't work properly. What I tried to do is to get the user chose value to 'select' variable. But it doesn't work. It always gets the last element in ITEMS (this list is defined in db.py). My next option would be to be call another controller function, passing the user selected value as an argument. Then it can prepare the form with the passed value and send to a view to display
<h2>Input form</h2>
{{=form}}
But I'm not sure how I can assign the user chosen value to an argument and then call another controller function with that arugument value.
If you have any suggestion how I can modify this to get the user chosen value thats very much appreciated. Thank you.
You could create a <select> element listing all the tables, and then load the form associated with the selected table as a web2py component via Ajax. In the view of the main page (e.g., /views/default/index.html):
<script>
jQuery(function() {
jQuery('#table').change(function() {
web2py_component("{{=URL('default', 'form.load')}}" + "/" +
jQuery(this).val(), target='form')
})
})
</script>
{{=SELECT('Select a table', *db.tables, _id='table')}}
<div id="form"></div>
And in a controller (e.g., default.py):
def form():
if request.args(0) in db.tables:
response.generic_patterns = ['load']
return dict(form=SQLFORM(db[request.args(0)]).process())
else:
raise HTTP(404)
Note, db.tables is a list of all the tables defined on the db connection object -- it is used in the SELECT() helper in the view to generate a <select> list of all the tables. The script in the view registers a jQuery event handler that fires whenever a different table is selected from the dropdown. The handler calls the web2py_component() function (which is in /static/js/web2py.js), which loads the form component via Ajax into the div with id="form". It appends the value of the selected table to the URL.
In the controller, the form() function checks for the db table name in request.args(0). It then sets response.generic_patterns so the "generic.load" view will be allowed (by default, generic views are only enabled for local requests). Alternatively, you could define your own "form.load" view, or even use a different extension (e.g., "form.html").
Because the form is loaded as a web2py Ajax component, the form submission will be trapped and submitted via Ajax as well, so it will not result in a full page reload.
